How to Classify This HS Code?

What products does HS 845910 cover?

This subheading covers "Way-type unit head machines" as defined by the World Customs Organization (WCO) Harmonized System (HS) Nomenclature. These are specialized machine tools designed for performing machining operations, such as drilling, milling, or boring, on a workpiece. They are characterized by a self-contained unit head that moves along a predetermined path or "way" to engage the workpiece, often used in automated production lines for high-volume manufacturing. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm their function as single-purpose machine tool units.

What falls outside HS 845910?

The following products are excluded from HS 845910: general-purpose drilling machines, milling machines, or boring machines that do not feature a self-contained unit head moving along a way. Also excluded are machining centers that combine multiple machining functions and tool changing capabilities within a single machine, as these are typically classified under HS 8457. Furthermore, standalone workpieces or fixtures intended for use with these machines, as well as separate power units or control systems not integrated into the unit head assembly, are classified elsewhere.

What are common classification mistakes for HS 845910?

A common error is misclassifying general-purpose machine tools or machining centers under this subheading. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the heading and any relative section or chapter notes. Way-type unit head machines are specifically designed for automated, linear movement of the cutting head along a fixed path, differentiating them from more versatile machines. Confusing these specialized units with multi-function machining centers or simpler drilling/milling machines leads to incorrect classification.

How should importers classify products under HS 845910?

The correct procedure for classifying products under HS 845910 involves a thorough examination of the machine's design and operational characteristics. Importers and customs brokers must verify that the machine consists of a self-contained unit head designed to move along a predetermined way for machining operations. Reviewing technical specifications, manufacturer's brochures, and consulting official tariff databases like the USITC HTS or EU TARIC is crucial. If uncertainty persists, seeking a binding ruling from customs authorities is recommended.

How is the duty calculated for products under HS 845910?

A specific way-type unit head drilling machine weighing 1,500 kg and declared at a customs value of $25,000 USD would attract a US duty of $1,250. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value ($25,000 USD × 0.05 = $1,250). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule (HTS) for subheading 8459.10.0000.

Which trade agreements reduce duties for HS 845910?

Several free trade agreements may reduce the applicable duty rate for HS 845910, including the United States-Mexico-Canada Agreement (USMCA), which can provide for Free duty rates for qualifying originating goods from Canada and Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also offers preferential rates, potentially Free, for originating goods from member countries like Japan. To claim these preferences, a valid USMCA Certificate of Origin or a CPTPP Certificate of Origin is typically required, depending on the origin country.

FAQ

What are the primary classification criteria for HS code 845910, 'Way-type unit head machines'?

HS code 845910 covers 'Way-type unit head machines'. These are specialized machine tools designed for performing machining operations (such as drilling, milling, boring, or reaming) on a workpiece. The key characteristic is their 'way-type' design, meaning the cutting tool or the workpiece moves along linear guides or 'ways'. These machines are typically used for mass production or high-volume manufacturing, often incorporating multiple machining heads or stations to perform sequential operations automatically. Distinguishing them from other machine tools involves identifying their fixed base or column and the linear movement of the machining unit along defined ways.

What are the typical import duty rates for HS code 845910 in major markets like the US, EU, and UK?

Import duty rates for HS code 845910 vary by country. For example:

  • United States: The U.S. Harmonized Tariff Schedule (USHTS) generally lists a Most Favored Nation (MFN) duty rate of 2.00% ad valorem for machines of this type. However, preferential rates may apply under Free Trade Agreements (e.g., USMCA, CAFTA-DR).
  • European Union: Under the EU's Combined Nomenclature (TARIC), the standard duty rate is often around 2.70% ad valorem. Specific preferential rates are available for goods originating from countries with preferential trade agreements with the EU.
  • United Kingdom: The UK Global Tariff (UKGT) typically shows a duty rate of 2.70% ad valorem for this code, with potential for reduced or zero rates under specific trade agreements.

It is crucial to consult the specific tariff schedule of the importing country for the most accurate and up-to-date rates, as well as any applicable preferential treatments.

How is the import duty for HS code 845910 calculated, and can you provide an example?

The import duty for HS code 845910 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the imported goods. For instance, if the MFN duty rate is 2.00% and a way-type unit head machine is valued at $50,000 USD, the duty calculation would be:

$50,000 (Customs Value) × 2.00% (Duty Rate) = $1,000 USD (Import Duty).

In some cases, specific duties (e.g., per unit) might apply, or a combination of ad valorem and specific duties. Always verify the exact duty calculation method and applicable rates with the customs authority of the importing country.

What documentation is typically required when importing machines classified under HS code 845910?

When importing machines classified under HS code 845910, standard import documentation is generally required. This includes:

  • Commercial Invoice: Detailing the value, quantity, and description of the goods.
  • Packing List: Outlining the contents of each package.
  • Bill of Lading or Air Waybill: As the contract of carriage.
  • Customs Declaration: A formal statement to customs authorities.
  • Certificate of Origin: Especially if preferential duty rates are claimed under a trade agreement.
  • Technical Specifications/Manuals: May be requested by customs to verify classification and ensure compliance with safety or technical standards.
  • Import Licenses/Permits: Depending on the destination country's regulations for machinery.

Importers and customs brokers should confirm specific documentation requirements with the customs agency of the destination country.

Which trade agreements commonly offer preferential duty rates for HS code 845910, and how can importers benefit?

Many trade agreements offer preferential duty rates for HS code 845910. Examples include:

  • USMCA (United States-Mexico-Canada Agreement): Goods originating from Canada or Mexico may qualify for duty-free entry into the US.
  • EU's network of Free Trade Agreements: Agreements with countries like Japan, South Korea, Canada, and many others often provide reduced or zero duty rates for industrial machinery.
  • UK's Global Tariff and Trade Agreements: The UK has established trade agreements with numerous countries that can reduce or eliminate duties on imported machinery.

To benefit, importers must ensure the machines meet the rules of origin stipulated in the relevant trade agreement and possess a valid Certificate of Origin or other acceptable proof of origin. This requires careful record-keeping and verification of the manufacturing location and production processes.
